GEARING FOR WASHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 761,951, dated June 7,1904. Application filed October 13, 1903. Serial No. 176,874. (Nomodel.)

To all whom it may concern:

Be it known that I, HER AN JOHN DUVE, a citizen of the United States,residing at Davenport, in the county of Scott and State of Iowa, haveinvented new and useful Improvements in Gearing for Washing-Machines, ofwhich the following is a specification.

This invention has relation to washing-machines; and it consists in thenovel construction and arrangement of its parts, as hereinafter shownand described.

The object of the invention is to provide a washing-machine having ashaft adapted to rotate in fixed bearings, said shaft being providedwith -a gear-wheel adapted to engage pins or teeth on a collarsurrounding the dasher-shaft. A yoke is fixed to the dashershaft, andthe said collar is pivotally supported at an intermediate point to saidyoke. The said collar is provided with an upper and lower set ofgear-teeth or pins and an intermediate horizontal rib with curvedflanges located beyond the ends of said rib. The horizontal shaft isprovided with a gear-wheel which is adapted to engage alternatively theupper and lower sets of gear-teeth of the said collar, the end of thesaid shaft extending past the edge of said rib and adapted to hold thegearwheel in engagement with the lower set of gear-teeth of the collar.The side of the said gear-W heel is provided with pins or lugs, whichare adapted to come in contact with the curved flanges of the collar,and thus oscillate the said collar, whereby the said dasher is caused torotate back and forth, while the horizontal shaft rotates continuouslyin one direction.

.In the accompanying drawings, Figure 1 is a vertical sectional view ofthe washing-machine. Fig. 2 is a top plan View of the same. Fig. 3 is avertical sectional View of the oscillating collar and its attachments.Fig. 4 is a side elevation of said collar flattened out, showing therelative positions of the gear-teeth, rib, and flanges and also showingone position of the gear-wheel (in dotted lines) with relation to saidcollar. Fig. 5 is aview of the collar the sameas Fig. 1, showing therelative position of the gear-wheel (in dotted lines) when about in theact of oscillating saidcollar.

The tub 1 is mounted on suitable legs 2 and ings 16 and 17.

is provided with a hinged top 3. The dasher 1 is fixed to the lower endof the dasher-shaft 5, which passes vertically through the center of thetop 3. Said dasher-shaft 5 is journaled in the bearings 6 and 7 The yoke8 is fixed to the dasher-shaft 5, and the collar 9 surrounds the saiddasher-shaft and is pivotally connected at an intermediate point to theyoke 8, as at 10. The said collar 9 is provided with an upper set ofgear-teeth 11 and a lower set of gear-teeth 12, and midway between thetwo sets of said gear-teeth is located a horizontal rib 13. The saidcollar 9 is alsoprovided beyondthe ends of the rib l3 with the curvedflanges 14.

The shaft 15 is adapted to revolve, but is held in fixed horizontalposition by the bear- The gear-wheel 18 is attached to said shaft 15,and the inner end of said shaft extends past the outer edge of the rib13.. The inner face of the gear-wheel 18 is provided with the pins orlugs 19, which are not long enough to engage the rib 13 as the saidgear-wheel 18 rotates, but are adapted to engage the curved flanges 14:and oscillate the collar 9, as will be hereinafter explained.

The shaft 15 may be provided with a hand operating wheel 20-, as shownin Fig. 1, or if it is desired to operate the washer at a faster rate ofspeed the said operating-wheel 20 may be attached to a shaft '21, uponwhich is located a larger gear-wheel 22, which meshes with a smallergear-wheel 23, located upon the shaft 15. The machine may be operated byhand or power, as desired.

The operation of'the machine is as follows: i

The shaft 15 rotates in fixed horizontal position, the gear-wheel 18engaging one of the sets of gear 11 or 12 of the collar 9. The saidcollar is carried around, Which through the yoke 8 causes thedasher-shaft 5 and dasher 4 to make a partial rotation. VVheu the end ofthe rib 13 is brought to a point beyond the end of the shaft 15, one ofthe lugs 19 comes in contact with the inner surface of the curved flange14, and the said collar 9 is moved either up or down, (according to thedirection on which the shaft15 is turned) and the teeth of the saidge'ar-wheel18 will engage the other set of gear-teeth on the collar 9and cause the said collar and its attachments to rotate back in theopposite direction.

Having described my invention, What I claim as new, and desire to secureby Letters Patent, is

1. A shaft adapted to rotate continuously in one direction, a secondshaft adapted to rotate back and forth, a yoke having both its endsengaging the last said shaft and an intermediate portion bowed away fromsaid shaft and adapted to move With said shaft, an oscillating collarlocated upon the last said shaft said collar being pivotally supportedat a point intermediate the ends of the said yoke, and a suitableconnection between said collar and the first said shaft.

2. A shaft adapted to rotate continuously in one direction, a gear-wheellocated upon said to this specilication in the presence of twosuhscribing witnesses.

HERMAN JOHN DUVIG.
